The built environment and the determination of fault in urban pedestrian crashes

Historical context and legibility of fault

• Several comments connect the paper’s themes to earlier critiques of auto safety and the idea that vehicle defects and road design were historically “illegible” in crash reporting.
• Another cited history-focused work argues that US streets were socially reconstructed to prioritize cars, not an organic evolution.
• This is challenged by others who note that pre-car cities already separated pedestrians (sidewalks, crosswalks, vehicle bans at certain times) and that streets were dangerous even with horse traffic; there is disagreement over how “mixed use” historic streets really were.

Signal design, turning movements, and pedestrian risk

• Multiple anecdotes describe pedestrians being hit or nearly hit when left-turn arrows or permissive left turns coincide with walk signals.
• Some argue this is normal design: pedestrians have priority, but drivers turning on green must yield.
• Others note that short green arrows encourage risky, rushed turns and that A-pillar blind spots and multi-lane roads worsen visibility.
• One commenter describes more sophisticated controllers that stagger pedestrian and left-turn phases, but notes trade-offs in cycle time and driver complaints.

Cars in cities, walkability, and land use

• Strong claims that private cars “do not belong” in cities; crashes are seen as a design failure, not just individual error.
• Many examples of US environments where walking even a short distance is unsafe or impossible (no sidewalks, hostile arterials, roundabouts, 6‑lane roads without crossings).
• Counterpoints stress economic impacts of limiting cars and note that in most US cities the vast majority of commutes are by car.
• Debate over whether people “want cars” intrinsically or are responding to infrastructure and policy; non-US and high-transit cities are cited (briefly) as contrasts.

Design standards, geometry, and policy constraints

• Discussion of national standards (e.g., minimum lane widths, turn radii) that embed car-centric assumptions and create legal/liability barriers to narrower, slower streets.
• Some argue cities still have tools (parking limits, congestion charges); others say these don’t fix core design issues like lane width, crossing distance, and turning speed.

Responsibility, data, and fault assignment

• Several comments unpack the paper’s claim that focusing on individual fault (driver vs pedestrian) obscures systemic contributors: street layout, speed expectations, signal timing, land-use patterns.
• A detailed example of an icy-hill crash illustrates how many factors (weather, road design, maintenance, transport options) can matter but are often excluded from crash coding.

Speed, normalization, and crash factors

• One highlighted finding: speeding did not significantly affect fault assignment in the studied data, interpreted as social normalization of speeding.
• Others suggest the distinction between “speeding” (rule-breaking) and “speed” (design speed chosen by agencies) is key; the latter may be more important for safety but is not treated as individual fault.
• Some note local examples where speeding is under-recorded due to how statistics are gathered, or where most severe crashes involve speed even if not coded that way.

Street width, layout, and perceived safety

• Many observations that wide, straight “stroads” encourage high speeds, late braking, and red-light running, while narrower, one-way or winding streets feel safer and often move people just as effectively.
• Comments describe the “feel” of a street (lane width, parking, curvature, surface, vegetation, raised crossings) as a major driver behavior cue.

Visibility, blind spots, and lighting

• Concerns about vehicle blind spots (A-pillars, bus mirrors) obscuring pedestrians, especially on turns.
• Nighttime lighting and glare from “security” lights are described as creating blind zones where pedestrians suddenly appear.
• One pedestrian reports using a high-intensity flashing light aimed at drivers in crosswalks to avoid being hit; others criticize this as potentially blinding and unsafe for all road users, illustrating tension between individual survival tactics and system-wide safety.

Abstract and clarity of the paper

• A few comments find the paper’s abstract unhelpful or confusing, particularly around the phrasing of “designation of individual responsibility” and how exactly that blocks design interventions.
• Others rephrase the core thesis as: overemphasis on pedestrian fault and underemphasis on built environment and systemic design prevents safer redesigns and policy change.
